问题：Get无法解析有效composer.json上的版本约束。

我有 /srv/www/site/api/composer.json 和 /srv/www/site/frontend/composer.json 。目录/ srv / www / site / api /和/ srv / www / site / frontend /

中没有 composer.lock 或 vendor /

Api composer.json和frontend composer.json包含相同的文字：

{
    "minimum-stability": "stable",
    "require":
    {
        "doctrine/dbal": "*"
    },
    "autoload":
    {
        "psr-4":
        {
            "app\\": "./"
        }
    }
}

首先。我跑了。

cd /srv/www/site/api
composer install

得到结果。好的。

  - Installing doctrine/annotations (v1.2.7)

  - Installing doctrine/common (v2.5.1)

  - Installing doctrine/dbal (v2.5.2)
    Loading from cache

doctrine/dbal suggests installing symfony/console (For helpful console commands such as SQL execution and import of files.)

二。我跑了。

cd /srv/www/site/frontend
composer install

得到结果。错误。

  [UnexpectedValueException]                                       
  Could not parse version constraint >: Invalid version string ""  



install [--prefer-source] [--prefer-dist] [--dry-run] [--dev] [--no-dev] [--no-plugins] [--no-custom-installers] [--no-autoloader] [--no-scripts] [--no-progress] [-v|vv|vvv|--verbose] [-o|--optimize-autoloader] [-a|--classmap-authoritative] [--ignore-platform-reqs] [packages1] ... [packagesN]

如何解决？这是错误还是失败？

Answer 1

只需删除用户目录中的.composer文件夹即可。对我来说 /home/noopic/.composer 。在两个目录中成功安装。

但如果我在前端跑步

composer update

得到同样的错误。

作曲家。错误：＆＃34;无法解析版本约束......＆＃34;在有效的composer.json上
